HI folks,
I have a pair of Urei 809 coaxial speakers. They were well regarded in their age ( 20 years ago) but now, I feel that they are sounding old for today standards.
They are coaxial speakers with a 12' woofer from Altec and a distinctive blue horn driver. They have a very complex passive crossover with a "time align" feature. (They delay the woofer some nanoseconds.)
Problems:
1-Lack of "definition": I like the punch of the new biamped designs like Dynaudio and Genelec.
2-Hi end sinking: they begin to fade out from 7K at 6-7 db/oct
3-Some small but unpleasant sense of distortion on the treble zone from 5K and up
So I'm considering to retire the passive crossover and triamp them, adding a tweeter to cover the zone from 5K to 20K.
I'm aware that I'll have to time align the system but I think is worth it. Can anybody suggest a nice tweeter to complement this system? How about a Scan-Speak D2905/9500?
As the system is going to have an active crosover with separate amps for the drivers, I asume there is no need to get a tweeter that matches the efficiency of the horn. Am I correct?
Thanks for any advice on this.
Cheers
Ric

Hi,
I would still regard them well, though even in their day I felt that the bigger Urei's where much better.
You could do that, if you do I think you best go straight to a high quality digital X-Over with options for electronic time alignment and equalisation.
However, I have a sneaky suspicion that your 809's are nowhere near what they sounded like new. Most likely wiring and x-over components have degraded and possibly the drivers where overloaded. I would suggest to have the drivers checked out first, then to re-build the pasive X-Over (capacitors and variable resistors especially) and finally to replace the internal wiring and to ensure the X-Over controls are correctly set via a spectrum analyser and to then replace the Pot's by pairs of fixed resistors.
SCAN SPEAK 2905? To match a 1" Exit Compression Midrange!!!!!???? You have to be joking.
In terms of strict "technically correct" behaviour with pseudo anechonic measurements - yes. You may find the sound to integrate extremely badly. Try a bullet type supertweeter and do not let it operate below at least 10KHz, the 1" Exit compression driver will work fine up to that point with some basic Equalisation.
Otherwise, if you want that compressed and distorted sound produced by modern low sensitivity speakers (like Dynaudio or Genlecs small monitors) you need to get such speakers. Much of the "punch" IMNSHO is simple transient thermal compression in the voice coil of woofer and tweeter, plus gobs of distortion.

PS, I agree with Nelson Pass - anything under 98db/1W/1m is hopeless for high quality audio.

Urei story
First at all, let me tell you what the complete Urei speakers story is,
I was moderatly happy with the Ureis in my 3.5 by 6.5 meters studio (I use them for post-producction work-mixing for Picture ). Then I bought a pair of Genelec 1030. The Genelecs are little biamped two way speakers with a 6" woofer and 1" tweeter in a tuned box, not sealed.
Genelec 1030 specs URL in case someone wants to take a look:
http://www.genelec.com/products/1030a/1030a.php
My plan was to use the Ureis for the far/mid field and the Gernelecs for near field monitoring so I installed the Gens and something amazing happened : Suddenly a new sonic universe opened up. Things that were not there before apeared . Articulation was exelent, no distortion, clear mids. Of course no bigl bass, they are 6" speakers after all.
I think the main difference is the treble extension and the absence of distorsion and that is what I want to fix on the 809's side (if it's possible, of course).
You could say that if I like the Gens so much why not to buy a pair of big ones and forget the Ureis?
Well. two reasons:
1-Big Genelecs : U$S 20 K. Way out of my range.
2-Somehow I suspect that something good can be done with these Urei speakers besides dumping them in the trash.
Now I honestly ask-from my ignorance in the high art of speaker design: Can I do something meaninfull to fix the Ureis?
And Mr Wang, I'm not joking. It's just that I'm not a speaker designer, so I humbly come here to ask to the people that realy know. That the only wat to learn, right?
So, what is a bullet tweeter and why is better than the 9500? That, and a few other things, I'd really like to know.
cheers

Hi Ric
Don't mind our friend Kuei, he gets a bee in his bonnet about certain things😉, but he is also well worth listening to on other occasions. ( I did think you might have chilled out now you have a new interest in life though, Mr T😀 )
As you are audio aware, to help diagnose the problem you have it would be worth measuring the response of your speakers, (a cheap computer mic and shareware FFT prog will do the trick), and then we can work out what may be going wrong and how to implement a solution.
You may want to look at this Morel tweeter though as a possible option, it means you could keep your cabinets stock, and not damage the resale value

Re: Urei story
Hi,
To make this simple. The Crossover on the tweeter section contains two trim pots. They will loose contact over 20years. Some of the capacitors are likely bipolar electrolytic and thus will have aged and be out of spec. The wire in those days was stranded copper and it will likely have oxidised.
Drivers age too, the woofers suspension may have hardened (or gone loose) and the magnets may have lost strength especially if the speakers where played at high level. I am not saying that any of the above is invariably the case, but chances are good that some items at least are amiss.
Also as, mentioned, the settings of the two trim pots strongly influence the frequency response and hence sound. Also, your Amp on the Ureis may be apst it's prime (electrolytic capacitors should be changed every 3 - 5 Years to make sure they do not age and end up out of specification.
So, maybe with a decent new Amp and or a refurbishment of the old one (let me gess, an Amcron bought with the UREI's? Yes? No?) and a refurbishment of the speaker to get backj to it's original specs, plus correct setting of those pot's will remind you what a real monitor can be like. I know the small Genlecs. Not my cup of tea. Compressed, lacking in low end and SPL capability and that is from a home viewpoint, never mind studio.
As for what is a bullet Tweeter, it's for example a JBL2402 (IIRC), though as supertweeter the Fostex FT-17 is better suited. The main advantage over dome tweeters is amuch better top end, transient response, sensitivity and sound.

Cheap is betterrrrr......
So this Fostex bullet thing is better than the SS 9500? Very good news, it cost only U$S 35. That's 100 bucks cheaper than the SS. Thinking about ordering a couple.
I'll follow Pinkmouse suggestion to conduct some tests with the proper equipment to see exactly what's going on and I'll report back.

I agree with Thorsten. The FT17H is a great little tweet, and for the price, a gift.Ricren said:
Some measurements
I just made a couple of fast and dirty mesurements of the 809 speakers. For reference, they are instaled flush mounted in a wood wall. The readings was taken with an Earthworks TK30 presitiion microphone into a Milennia Media pre going into an 828 Motu 24 bit audio interface and Spectrafoo. The distance from mic to speaker was 1 metre, injecting pink noise directly into the amp -a JBL 6230 THX aproved amp.(?).
First I measured the response of the amp taking the signal directly from the speaker terminals: Table flat.
Then I measured one speaker and then the other. Amazingly they measured more or less the same. You can see the highs rolling of at about 9 db/oct from 8K to 16K. Here's the curve:
And the hiped low end, an effect described in the Urei manual caused by the flush mount technique. I use a digital eq between the mixer and the amp, but for this measurements It was out, of course.

Gen curve
I can add that the speakers were tested a month ago at the JBL local representative. (Urei was bought by JBL many years ago). They changed the woofer suspension foams (they were de-integrating badly ) and cheked the drivers. They say they are ok. But they did not test the crossover.
Additionally a friend of mine that has experience repairing compression horns suggested (and did it ) to disasembly the mid/high driver to re-center the moving coil and search for fungus build up. They were clean and emerged from this test Ok.
I could say that they were not abused during these years.-in TV post production your SPLs are low, not like pop/rock music mixing which is a completly different situation.
For comparisiion, I run a test on the Genelcs and this is the curve.
Next test? I accept suggestions. I think I could measure each driver separately without the crossover.

Re: Some measurements
Hi,
I do appreciate your attemps to measure the performance of your speakers, but do you actually sit in 1m distance from them?
Also, a simple flat response (my own system can be adjusted using a digital EQ to +/-0.5db flat with third octave weighting at the listening position 20Hz - 20KHz if should wish so) does not necessarily imply a realistic sound.
Again, I appreciate that you are saying "UREI don't do it for me", which is fine. Some of my best friends actually consider Quad ESL's or BBC LS 3/5's to be "good speakers".
For my personal take, give me a decent 50W Valve amp and a pair of "original spec" 809 or better 813 or 815's and I'll be jolly happy. Give me a pair of Genlec 1030 or active Dynaudio's and I retch.
Sayonara
PS, I use Tannoy 15" Monitor Red myself, with valve amp's and digital room correction.

Ok Ricren, first thoughts on the graphs.
Assuming the scale on the left hand side is dB, then it looks like your tweeter is running at about 6db higher than the mid/bass, this may be causing the treble distortion you are hearing. I suspect that a previous owner was unhappy with the top end roll off, and tried to compensate by turning up what is left.
You could rebuild, as Kuei suggests, and that would probably be worthwhile, as the crossovers will be getting very tired after 20 years in a studio working.
But what I would suggest, as you are a commercial enterprise, your local pro audio dealers would be more than likely to lend you some demo crossovers, and you could try bypassing the passive XOs, and see if you like the results. If this improves the basic sound to something you and your clients like, and can work with, then you can think about adding a super tweeter to sort out the high end roll off.

Re: Re: Some measurements
The purpose of the '1 meter measurement" was-as is suggested often - to measure just the response of the speaker, not the room or their mutual interaction.
We agree. More that that: I was so aware that I did not write: "performance test results" but instead "some measurements". In fact I was just following Pinkmouse's suggestion:
As you are audio aware, to help diagnose the problem you have it would be worth measuring the response of your speakers, (a cheap computer mic and shareware FFT prog will do the trick), and then we can work out what may be going wrong and how to implement a solution.
And I also appreciate that you say "Gens don't do it for me". But what I'm really saying is: "these particular pair of Ureis don't do it for me in their actual state and after listening to the Gens, I realize they have certain element that is missing in the Ureis that I'd like to ADD."
To put it simple, I, for one do really enjoy listening to tubes and Tannoys. We have a local audio club and we organize "listening partyes" with all sort of equipment, branded or home built, and to be fair, the high emotional spots are generally associated with tube rigs.
But also I feel that for "clinical" kind of listening, like the one you do in a mixing session, the SS systems are better suited to the job, hands down. But hey, that's only my personal view, of course. And I will not propose it as gospell. I'm an educated fellow.
Take care, Twang
And I do really apreciate your input.

You are right, but it was not a previous owner-I bought them new about 15 yeas ago-I did that "sacrilege" myself. What can I say? I miss the treble....
Again you are right. But let me tell you something: I'm not taking this from a strict commercial point of view, because if I factor the time and work is going to take the right research for the refurb process, is way cheaper to just buy a pair of new and ugly big JBLs bearing in mind that with them on board, no client would argue.
But you know what? I personally want something better for me. I want to tweak them; after all I've been tweaking devices since 20 years ago. I'm not a speaker designer, as I said before but I'm here to learn, is going to take some time and effort, but I'm committed to take the jurney. This is what I like.
So. Following your advice I'll borrow/built/construct/program some crossovers and get some amps to attach directly to the drivers. (Some inverted gainclones, perhaps?)
I'll post the results. It's going to be fun.

Sumertime break
So apparently I'll have one week break on the booking of the mix room between projects, so it's time to dig deeper on the Ureis.
First I extracted one coaxial driver from the right channel and unsecured the crossover board to thake a look.
Attached are pics of one driver out of the box and a couple of views from the crossover board, where you can see the ELECTROLITIC capacitors that are not paralelled with film ones or nothing....
Notice the distance between voice coils of the two drivers. Someting like 12 centimetres! Now I realize why the Urei people were so heavy into highlighting the time align feature of these monitors. Without it, this thing would sound really bad.
Tomorrow a fellow sound enginneer will come to take some measures with Smaart. I'll post the results.

A few measurements finally:
Gear used: Smaart sound test software with a TK30 earthworks condenser microphone.
First test was to measure the tranfer function of the crossover board. An 8 ohms resistor was used to load the output instead of the speaker.
The first thing you do in smaart is to measure the time delay. It revealed a delay on the woofer output of 0.44 ms or 14 cm. The dealy on the horn side was 0.
I apologise for the fuzzy images, but Smaart was running on a laptop PC and the guy did not know how to transform the screens in a graphic format that I could pick, so I just taped the screen with a camcorder.
I'm used to do screen dumps all the time in Mac computers using shift-command-3 to get a pict document. How can you do it in a PC? Surely it's a way.
More tests soon. Any suggestions/comments?

Ric

Urei 809 for sale
Hi, I have a pair of Urei 809 speakers, they were in my studio for some years and are still in great condition. A couple of years ago i changed my monitoring system to an active JBL set up and stored my 809s away. Would anybody be interested in having these speakers of me, just make me an offer. This site would be better then EBay i think. Thanks for your time.

The drivers in the 809 are JBL's not Altecs. Compression driver is a 2416 and the Woofer is a modified 2214. Same exact componenets as a JBL 4425 in a different set-up.
Looking at your curves something not right as the 2416 can get you out beyond 16k. Are there stock diaphrams or aftermarket on the compression drivers??

Hi Rob,
They are stock ones. I bought the speakers new in 1994 and never changed the horn diaphragms.. You suspect could be something bad with them?
I did change the woofer suspensions, however.
I never abused them in any way, used indoors at my Tv post studio as the "middle-big reference speaker". Meaning that most of the time they were off, because we use to mix tv material with little speakers and occasionally we check with the big ones.
